In our case, we had crashes which seemed to be caused exactly by this
issue, OpenGL resources were freed and we suspected that they should
have been freed within the Event Dispatch Thread and not by the Java
garbage collector.  But we could not produce a simple test case, so
this was only a wild guess.
I will test Luke's patch soon to see if it works for us.
